I just want to report that I had this problem with Tribe 3 (more information under http://ubuntuforums.org/showthread.php?t=511716) and Phillip's iso fixed it for me. Now after system boots it states in this only-a-cursor-and-plain-background state noticeably longer than under 7.04, but than screen turns black for a second and gnome starts in about 2 seconds.
